CHARLES DE QUILLFELDT, OF NEW- YORK, N. Y,A

slm-ion.-

SPECIFICATION forming part of Letters Patent No. 248,147, dated Octoberv 11,

Application filed July 30, 1881. (No model.)

To all whom it may concern l Be it known that I, CHARLES DE QUILL;r FELDT, of the city, county, and State of New; York, have invented certain new and usefui Improvements in Siphon-Bottles, of which the following isa specification.

This invention has reference to improvements in siphon-bottles for aerated liquids, whereby the opening and closing is obtained in a simple and reliable manner, with less liability of the mechanism to get outof order and admit the escape of gas, as is the case in the constructions heretofore employed.

The invention consists of a siphon-bottle, the month of which has an interior screw-thread for screwing in the threaded shank of the siphon, which is-also provided with aninterior screw-thread for attaching by an elastic and cemented sleeve the liquid-conducting glass tube. The shank of the siphon has an annular flange or seat, which is fitted by its concave under side to the bottle-mouth. The siphon is provided with an interior tube in line with the glass tube, above which is arranged an elastic diaphragm,which is retained by the closing-nut of the siphon. Through the nut passes the screw-threaded shank of an axiallyturning cap, said shank bearing by a washer upon the elastic diaphragm, so as to press the same upon the extension-tube of the liquidconducting tube when the cap is turned in one direction, but release it when the cap is turned in the opposite direction, so as to admit theiiow of liquid through an annular chamber around the interior tube and the discharge-spout.

The accompanying drawingrepresents a side elevation of a siphon-bottle with the siphon shown in vertical central section. i

A represents a bottle of suitable shape, as usually employed for aerated liquids, and of a thickness to resist the pressure of the liquid charged into the same. t

B is the siphon, through which the aerated liquid is discharged from the bottle. Thesiphon B is provided with a discharge-spout, O, and below the connection of the latter. with the body of the siphon with a screw-threaded tnbular shank, a, by which it is screwed into the correspondiugly-threaded bottle-mouth, to which it is furthermore attached by a suitable cement or packing, so as to produce the intimate and rigid connection of the parts. The

BOTTLE.

`Vsiphon B is further provided below the spout' with an annular yflange, b, the under side of -which is eoncaved, so as to fit on the 'upper partof the bottle-mouth and retain the siphon reliably in position on the bottle.

siphon B is secured by means of an elastic sleeve-shaped packing, al, the central glasstube, D, through which the liquid is conducted to the spout C. Atube, D', is arranged at the interiorof the siphon B, in line with the glass tube D and as an extension of the same, the extension-tube D communicating with the discharge-spout b v means of an annular space formed around it by theexterior wall of the siphon. The upper end of the extension-tube D isabove the opening of the spoutand surmounted by a disk or diaphragm, E, of rubber or other suitable elastic material, which is 1etained bya nut,E, and a metallic ring-shaped washer on an interior shoulder, e, ot' the siphon B, the shoulder being below the upper end of the extension-tube D. The diameter of the diaphragm E is larger than the inside diameter of the siphon B, so that it forms a kind of arch over the extension-tube Dl and leaves a space betweentheoritice of the tube D and the diaphragm when the latter is not compressed by exterior means. In this position of the diaphragm a channel is provided for the free exit of the aerated liquid to the annular space around the extension-tube D', and thence to the discharge-spout C. The diaphragm serves the ltwofold purpose of closing, when pressed down, the liquid-conducting tube, so as to interrupt the flow of liquid, and prevent positively any leakage of liquid or gas at the top part of the siphon, which forms one of the objectionable features in the common siphon-bottles at present in general use.

The screw-nut E has an exterior shoulder nearits upper end, by which it bears on the top part of the siphon when entirely screwed in. A cap, F, screws by a threaded centershank, f, into the hollow center portion of the' nut E and presses a disk-shapedmetallic washer upony the upper surfacelof the diaphragmE, so as to close the extension-tube D' when the shank is turnedin two directions, while releasing the same when the shank is turned in opposite direction. The cap F is provided with a circumferential Hangs, g, around the upper To the inside of the tubular shank a of thev IOO - as new, and desire to secure by Letters Paten tpart of the nntE and the main piece B, said iiangefhaving a fixed inwardly-projecting pin, g', which moves in a recess, g2, of the nut E', so that the cap maybe turned in one or the opposite direction only as far as the recess g2 admits, by which motion the cap is sufficientlyl. The combination ot' a siphon having au interior extension-tube in line with the liquidconductingtube and an interior annular chamber around the extension-tube,with an elastic diaphragm above the extension-tube, an interior screw-nut for securing the diaphragm to the siphon, and an axially-movable cap having` a central screw threaded stem passing through the center of the screw-nut, substantially as set forth.

2. In a Siphon-bottle, the combination oi' a siphon, B, having an interior extension-tube, D', in lille with the liquid-coiulucting tube D, with an elastic diaphram, E, secured by a screwnut, E', with an axiallymovable cap-piece, F, turning by a screwthreaded shank, f, in the open central portion of the cap,and with means whereby the extent ot' axial motion of the cap is controlled, substantially as set forth.

In testimony that I claim the foregoing as my invention, I have signed my name, in presence of two witnesses, this 26th day of July, 1881.

CHARLES DE QUILLFEIJDT.'
